I don't trust rom manager to handle anything clockwork related on my phone, it screwed my d1 up all the time. Just boot into it manually, and also save yourself a headache and download the touch version of cwm, its epic.

How do you boot in CWM?
ROMManager says I have it... yet if I try:
1) reboot to CWM via Bootmanager, just goes straight back to normal boot
2) boot holding both vol up and down = boots to bootloader 0.3a
3) boot holding up OR down button = boots to moto flasher

But no clockworkmod recovery mode...

This is for the US version baseband N_01.81.00R

recovery-clockwork-2.5.0.1-sholes.sbf via RSDLite doesn't work either, via either of those flash loaders.
